This is an advanced sexual manuever that occurs when having intercourse with a female while she is positioned on her back with ass and legs up in the air. The male is standing during this encounter, but is hiding a secret....Just before ejaculating he pulls his dick out of her pussy, then the surprise....then he continues to pull his balls out of her ass, releasing all kinds of satisfaction!
